22 Claims. (C ting-ef The invention relates to flexible cord or ropemembers more particularly designed for use in forming robe railsforautomobiles and other uses. It is the object of the invention'to obtain5 a construction which is formed of inexpensive materials; hasiahighdegree fftensile' strength; maintains a round cross section'a'nd isexternally of a pleasi g appearance. It is a further object of theinvention to obtain a simple method. for o forming this construction.:Withthese objects in .view the invention consists in the, constructionand method as hereinafter set forth. In the drawing: I r

Figure 10 is an elevation showing a'robe rail of my improvedconstruction as attached I to .the seat of an automobile.

Gene ally described, my improved construction 2 of flexible rope isformed from strips .of fabric,

such, as burlap, which are impregnated with a plastic adhesive such aslatex. j'Ihese stripsare' then fed through guides which place the samein cross-sectionally overlapping relation, .after which they are passedthrough a converging guide for fashioning them into a spiral crosssection; Pressure is then appliedto condensethjis cross section, aiterwhich a surrounding ornamental covering is placed thereon. In'order thatthe rope may be maintained circular in ,cross section; it is desirabletospirally windthe'strips about a central core which also isv circularin cross section. For this 'core I may employ a paper cord, and toproperly place this core in the center of thespiralflwindingQl attach itto'a fabric strip whichis at one end of the overlapping series. Thus,[in the subsequent spiral winding of these strips they willremainfsubstantially parallel to this coreand after the final compres-45 sion will have a circular cross sectional periphery.

In detail, the method of forming my improved rope or robe rail isasfollowsz I A plurality of comparatiyelynarrow strips of fabric,preferably,burlap; are cut and are then immersed or otherwiseimpregnated with latex by suitable means Knotfshown); 'I he lateximpregnated strips A are then fed through "a series of guides B, B;etc., from which they emerge in overlapping relation. There is also aguide C forv 66 the paper here D. The strips and core are then Figure 1is a plan view of an apparatus which passed between rollers Ehaving'grooves E for receiving the core D and placing thesame over oneof thestrips, suchasA', and beneath'an overlapping strip A, as shown inFigurej3. This completely covers the core and attaches the overlappingstrips to each other,'the latex being sufficiently'adhesive to retainthe, elements inthis position. After leaving the rollers E the stripspassv through a converging guide F. which as shown in'Fig'ures .4 and 5is of spiral cross section with prpgre'ssively increasing' number ofconvolutions. From the? discharge end of this guide F the spirally"wound strips pass between presser rollers Gan d H which are providedperipherally with substantially semi-circular grooves. The roll I-IQ-is.alsoprovided with radially outwardly extending flanges H which overlapthe rollerG and form a complete-enclosure for retaining the spiralfabric. Thus the pressure of the rolls will condense the ..cros's;fsection and impart thereto a circular fpe' iph'ery which isconcentricwith the,

circular'core D.:

f To. impart the desired ornamental appearance to ,-the rope I- coverthesame with a suitable fabrics 'I'hisfisla strip I of such width as toencircle the .outer surface. of the rope bringing the opposite edgesof'the strip in abutting relation.

Howeven'in order to secure the cover in this position, 1 preferablyprovide a selvage edge J which is woven with the strip, but isconsiderably less in thickness. This' 'selvage extends along both edgesof the strip so that when thestrip is wrapped about .the rope oneselvage edge may underlap the body portion of theopposite edge of thestrip, while the selvage portion atthat edge is turned a back tofcoverthe first placed selvage. These two selvage portions will be cementedtogether by the latexwhich is in the rope, and after passing betweenpresser rollsK and L, similar to the rolls G and H, thecoyer will bevilrmlyattached to the rope. The wrapping of the cover strip about thelfope iseffected through a tapering spiral guide Msomewhat similar inconstruction to the guide F and which is placed in advance of therolls Kand L. The cover strip I may be fed into relation .to the rope over. aguide roller Nwhich is in advance of the guide M. i
